a
Strains are described in Boyd et al. (5).
b
Colony morphology and associated phenotypes were recorded after growth on T agar at 28°C for up to 10 days: pattern (rdar), colonies had complete surface patterns and could be lifted intact from the agar surface; incomplete pattern, colonies could not be lifted from the agar surface; no pattern, colonies were smooth and mucoid.
c
Fluorescence of colonies grown on T agar supplemented with 200 μg/ml calcofluor was observed under a 366-nm UV light source and compared to ATCC 14028 positive control and ΔbcsA negative control strains.
